The QPA9122 is a wideband, high gain, and high peak power driver amplifier. It provides 37dB gain at 2.6GHz and achieves a peak power of 27dBm P3dB. With a quiescent current of 95mA, the amplifier can provide good DPD linearity performance with wideband signals of up to 160 MHz IBW making it perfectly suited for mMIMO applications.
The QPA9122 is internally match to 50Ω over the entire operating frequency band of 2.3 – 5.0 GHz and incorporates a shut-down function through the VPD pin.
The QPA9122 is housed in a 16-pin 3X3mm SMT package and is footprint and pin-compatible to QPA9120 and QPA9121.
